After DEMI LOVATO went to that treatment center for . . . whatever it was she had to be treated for . . . she had to make some tough choices regarding the people she was hanging out with.

--She says, quote, "I did kind of a friend cleanse right after rehab, where I weeded out people who didn't have my best interests at heart.

--"Now I have friends who love me for who I am and don't care about what I'm doing.  Most of them aren't in the industry.  Some of them don't even know my songs!"
